Halohydrin Formation

Halohydrin formation alkene reaction mechanism tutorial videoAlkene Reactions Series: Video 4
This tutorial takes you through the halohydrin formation mechanism, a type of electrophilic addition which adds both a halogen and alcohol to an alkene by using water instead of an inert solvent like CH2Cl2 or CCL4 to yield a halohydrin which features both a halogen and alcohol on the carbon chain

This video provides with a step by step breakdown of the mechanism and helps you understand WHY this reaction undergoes anti addition and still follows Markovnikov’s rule.

    So helpful! This type of step-by-step explanation is much appreciated.

  2. you r truly awesome

    You make Organic chemistry so simple, thank you so much.

  4. so would this be considered anti addition since they add on opposite sides of the double bond and steriochemistry antimarkovnikov since the cl ended up on the less substituted carbon?

    • Careful there Mary. It’s anti-addition as you said, but follows Markovnikov’s rule since the OH adds to the more substituted carbon atom. Markovnikov’s rule is about the carbocation intermediate stability, and this molecule puts more partial positive on the more substituted carbon

  5. Can you have a step by step reaction for ozonlysis, and demercuration

  6. You are truly awesome!
